I guess I'm leaning toward a PC. I want to run up to three external screens, how much ram should I get? Will a USB port multiplier work? Or do I need to get a machine that has several HDMI ports? One of my platforms is written for a single-core processor and multiple cores don't speed up processing. What's the fastest single core available? Is that a bad idea?
According to Russel Peters, macbook is ‘stupid people friendly’ laptop, so if you don’t want to do much except analyzing trades and do some basic computer stuff, macbook will serve you well.
My theory is that if you can't answer your own questions and need advice from random people on the internet... you should just buy the "prettiest" machine you can afford. It'll be a toy at this point anyway and nowadays your money goes pretty far in terms of hardware. You'll figure everything else out along the way. Otherwise, forget the laptop and book some time on this thing. This advice may sound facetious but I'm being dead serious. ¯\_(ツ)_/¯
